Equipment suitable for automatically grinding end face of small cubic part

The invention mainly discloses equipment suitable for automatically grinding the end face of a small cubic part; the equipment can achieve automatic conveying and grinding of the small cubic part; theequipment consists of a conveying device (1), a rack (2), a feeding device (3), a grinding device (4) and a discharging device (5); the conveying device (1) can enable to-be-machined parts to be conveyed to the inlet of the feeding device (3) in a queue shape according to required postures; subsequently the to-be-machined parts are pushed to to-be-machined positions through a pushing rod (43) inthe feeding device (3) when a notch of a movable material separating plate (35) coincides with a notch of an auxiliary machining plate (34) in sequence; after a material suction nozzle (56) moves downwards to make contact with and fix the parts, a grinding wheel (48) is driven by a driving motor (47) in the grinding device (4); the grinding wheel (47) moves leftwards and rightwards through a thirddriving cylinder (45) whic
